Dutch OpenFOAM Users Group

This is the site of the Dutch OpenFOAM users group which has been active since 2010.

OpenFOAM is a C++ toolbox for the customisation and extension of numerical solvers for continuum mechanics problems, including computational fluid dynamics (CFD). It comes with a growing collection of pre-written solvers applicable to a wide range of problems. It is produced by the UK company OpenCFD Ltd. and is released as open source under the GPL.

There is a rapidly growing interest and development of OpenFOAM at universities, research institutes, and industries. It is an important platform for smooth and rapid transition of ideas, methods, and software developed at universities to research institutes and industries. Since it is open source all details of the used methods are available. Many companies are considering OpenFOAM as a cheap and flexible alternative to commercial CFD packages.

The growing interest in the Netherlands has led to an initiative for creating a Dutch OpenFOAM users group. The group is intended for the exchange of experience and expertise among OpenFOAM users in the Netherlands.

Introduction to using OpenFOAM for CFD analysis

On November 23, 2018 an introductory course in the use of OpenFOAM for computational fluid dynamics analysis will be given at the Faculty of Electrical Engineering, Mathematics and Computer Science of Delft University of Technology, in Delft.

The course is organized in the framework of the Dutch OpenFOAM user group (DOUG), by members of the Numerical Analysis group of the Delft Institute of Applied Mathematics (DIAM) and the Aerodynamics group of the Faculty of Aerospace Engineering of Delft University of Technology. This is the third time this course is taught and the organizers have used all the feedback from the first two editions to further improve the course material. There are now five tutorials available, and the participants can choose three that best suit their interest.

You will learn all the steps involved in computational fluid dynamics analysis using Open Source algorithms: geometry modeling, mesh generation, the actual computation and visualization for some basic applications. Additionally, you will be taught how to define a simple model in OpenFOAM. The course will almost entirely consist of hands-on Lab sessions, with only a brief introduction to the theoretical background of OpenFOAM. The complete program and learning objectives of the course are listed below.

Registration:

The maximum number of participants is 18. Please register early at https://www.aanmelder.nl/openfoamcoursenovember23as we expect that more than 18 people will be interested in participating. For members of DCSE this course is free, TU Delft students pay € 50,- for the lunch and course material. For other participants the costs are € 200,- (including lunch and course material).

Subjects:

* Basics of OpenFOAM discretisation and solution procedure* Geometry modeling with SALOME* Mesh generation with SALOME and conversion of meshes to the OpenFOAM format* Mesh generation with snappyHexMesh* OF application for incompressible flow* OF application for multiphase flow* Building your own model* Visualize computed results using ParaView

Learning objectives:

After completion of the course you will be able to:* Generate basic to moderate geometric models in SALOME* Generate an unstructured grid for viscous flow computations using the SALOME grid generator and the OpenFOAM tool snappyHexMesh* Simulate time-dependent turbulent incompressible flow* Simulate time-dependent incompressible immiscible two-phase flow.* Build a simple simulation model starting from a system of partial differential equations* Visualize your results using ParaView.

What do you get:

* A step-by-step tutorial* A live-cd/usb-stick to continue your work on your own system at home or in your office.

OpenFOAM Workshop on Industrial and Environmental flows

The 12th meeting of the Dutch OpenFOAM User Group will take place on October 30, 2018. Four speakers will give a talk on how OpenFOAM can be used in industrial and environmental flows.
